The name and unit colours of HMCS Acadia were revived in 1956 by the RCN when a new Royal Canadian Sea Cadets summer training centre was established at the naval base HMCS Protector on Cape Breton Island.
[2] Royal Canadian Sea Cadets would continue to receive training from 1965–1970 at the naval training base HMCS Cornwallis near Digby, and in the 1970s at the shore-based facility HMCS Micmac at CFB Halifax.
On July 29, 1978 the unit name HMCS Acadia was recommissioned for the fourth time (second time as a cadet training centre) at CFB Cornwallis, the base which housed the Canadian Forces Recruit School.
Each year Annapolis Basin Conference Centre, which is the current owner of the former CF base, hosted approximately 1,500 cadets and staff.
Due to the reduction of the number of CTCs to 12, HMCS Acadia was not included, and will not host cadets again as a training centre.
